improved means for scouring or abradi'ng the breasts of boot and shoe heels, to the end that such heel breasts having considerable concavity may be cut expeditiously and without cutting or deiacing the shoe shank:

My invention comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had toy the accompanying drawings forming part hereof, wherein, Figure 1 is a side View of a heel breast scouring machine embodying my invention; Fig. 2 is a plan view partly broken; Fig. 3 is a section on the line 3, 3, in Fig. l; Fig. 4 is a section on the line ll, 4, in Fig. l `Fig. 5 is a vsection on the line 5, 5, in Fig. l, and F ig. 6 is a sectional detail illustrating the shoe heel in operating position.

Similar numerals o'f reference indicate corresponding parts in the several views.

The numeral 1 indicates a suitable frame, preferably open at .the center, and at the corners or angles are rollers or pulleys 2, 3, 4, 5, over which passes an endless belt 6, around which belt is a sand-paper or cutting belt 7, which is supported byand carried along .with b elt 6. The rollers- 3, 4, 5, are shown provided with flanges for guiding the belts, and said rollers are mounted upon spindles 3a, 4a and 5"L carried by ,the frame. Roller 2-is shown provided with a ian'ge at its innerend but Y11a/sinoy flange at its outer end, and is -mounted to revolve upon spindle 2, upon which it may be held by a screw. Spindles 2, 3 an 1, but spindle 4 is adjustably carried by frame i Secured jupon a slide 8 for adjusting the tension of the belts and to take up slack thereof. Roller 2 does not project through the belts and is shown of less length than the Width of the belts so as not to come in Contact with the shankv 9u of the shoe when Fonthis purpose slide 8 at iis marginal edgeafa 5 are secured upon frame '1, for which ypurpose said."spindle is spindle 3a .provided with. pulley/s 23, 24 on the sitethe belts (Fig). riheinzwhine may mm n Specicaton of Letters Patent.

lVhen the breast of the shoe heel istol be scoured, theshoe is held (in the positionshown in Figs. l, 2 and 6) with the breast of the heel against the sandpaper or abrading belt 7 alined with the outer portion of the roller 2, so that the shank of the shoe at the junction of the close against the vouter edge of the belts,

and thus as the breast of the heel is held against the curved abrading belt the heel,

By preference the inner edge of belt 6 is beveled at 6*1 so as not to engage the shank 9EL f (see Fig. 6). this means the heel breast may be quickly and con veniently scoured and thesole may be set Within the belts, 'as il'lu strated and the shoe may be moved in various positions as required according to theshape. of the heel.

being scoured.

By means of my improvements it will be understood that the heel may be quickly and 'properly scoured Without danger' of injury to other parts of the' shoe: As the sandpaper belt 7 is detachably applied upon the permanent' beltff the sandpaper belt maybe readily removedand replaced and the belt 6 ,will .carry the; belt 7 'along 'so that strain on belt 'fis materially reduced, Ienabling a relativelyweak abrasive belt' to be used.
